Bearing Application Requirements

Given the tight constraints – regulatory, engineering, and cost-related – surrounding electrified train and streetcar projects, finding even minute ways to reduce weight can pay big dividends in the long run.

For example, a pantograph is a jointed framework that conveys current to a train or streetcar.

GGB Railroad Bearing Solution

MLG is a value-engineered,filament-wound bearing for lighter-duty applications (like trains and streetcars) that still require the shock, misalignment, and chemical resistance of fiber-reinforced composite bearings.

MLG self-lubricating plain bearings have the same operating temperature range (-195°C to 160°C) as our high-end fiber-reinforced composite solutions, and feature similar low-friction and high-load capacity.

GGB Railroad Bearings - Benefits

Using MLG filament wound plain bearing for your pantograph offers the following benefits:
